Impact of DLC programs levels on reliability improvement of smart distribution network considering multi carrier energy networks

Abstract

In modern Smart Grid paradigm, through introducing demand-responsive proactive consumers, energy storage systems and renewable energy resources spread across the distribution network, the inherent of the service restoration problem changes from an all-or-none solution to selective restoration through smart meter and Distributed Energy Resources (DERs). Combined Heat and Power (CHP) is a great example of the technologies which allows coupling of multi carrier energy networks such as gas and electricity together in response to future energy infrastructures. In this paper, a practical and initiative method is presented to obtain the most optimal arrangement of supplying loads in each micro grid based on Energy Hub approach. In this paper, we examine the effect of various procedures of DLC programs (such as interrupt at the level of transformers or small groups of customers) of Demand Response (DR) on reliability indices in multi carrier energy networks. Simulation is applied on a 33 bus radial distribution network which supplies by two CHPs. MATLAB is employed to determine optimal combination of selected loads and transformers. Due to failure rate and repair time of each section, Outage cost, ASIDI and ENS indexes are calculated. Simulation results show that DLC at the level of small groups of customers reduces huge total costs 11-12% and 3-4% in comparison to DLC at the level transformers and without DLC program, respectively.
